Exploring Parts of a Computer
In chapter 1, we learnt about the computer. Now, let us learn about the different parts of a computer.
A computer has three types of parts. These are input devices, output devices, and storage devices.
We already know that a device is a tool that helps us to do a specific task. Now, let us learn about the different devices in a computer.
Input Devices
Can you name a few devices in the classroom? Think and Tell
Computers can only help us if we tell them what we need.
Input devices help us to tell a computer what to do. Input devices provide ways to ‘talk’ to the computer.
There are different input devices. Let us learn more about them.
Keyboard
A computer keyboard is a board with buttons on it. These buttons are called keys. Each key on the keyboard does one type of thing only. Using the keyboard, we can type on the computer.
A standard keyboard has 104 keys. You can find more keys on a multimedia keyboard, which is used for playing audios and videos. Did You Know?
Mouse
A computer mouse is a small input device. The mouse is used to move the pointer around the computer screen and click on files or icons to use them. It has two buttons and a wheel between them.
Uses of a Mouse
• Pointing at things on the computer screen.
• Moving pages on the computer screen up and down.
• Selecting items.
• Clicking on items to open them.
Microphone
The first mouse was made of wood and had two wheels underneath it. It was invented by Douglas Engelbart. Did You Know?
A microphone is an input device that lets us use our voice to tell the computer what to do. Microphones these days are fitted into the computer itself. We can also buy microphones that can be plugged into the computer.
Uses of a Microphone
• Recording our voice.
• Talking to other people while online.
• Giving voice commands to the computer to play music, search for a film, or open a file.
Do It Yourself 2A
Write T for True and F for False.
A device helps us to do specific tasks.
You can select items on the computer with a mouse.
The microphone helps us listen to the sounds made in the computer. The keyboard helps us to type on the computer.
The mouse has only one button.
Output Devices
We learnt that input devices help us tell the computer what we need. But how does the computer show us the results of our commands? It does so by using output devices.
Output devices show the results of what we want from the computer. Let us see some output devices.
Monitor
A monitor is the screen of your computer. It shows you the result of your input.
Uses of a Monitor
• Helps us to see what we are doing on the computer, like typing or moving the mouse.
• Lets us watch videos or films.
Explore More!
Do you want to know what is inside a monitor? See here!
Printer
A printer is used to print text or pictures on paper.
Uses of a Printer
• Lets us get a printout of text or pictures.
• Lets us get a black-and-white or colour printout of the text or the picture that we are printing.
Speakers and Headphones
Speakers and headphones help us to hear sounds that a computer creates as outputs.
This includes listening to music on the computer. It also includes listening to the voice of a person we have called using the internet.
Speakers are different from headphones.
Speakers are used when more than one person wants to hear the sounds and music. So, they are usually bigger.
Headphones are worn over the ears. They are meant for only one person to listen to sounds and music, without disturbing others.
Uses of Speakers and Headphones
• Helps in listening to music or sounds in a computer.
• Helps in listening to the voice of the person who we have called using the internet.
Storage Devices
Hard Disk
A hard disk is like a box that stores all the data in the computer. Every computer needs a hard disk to remember things.
Uses of a Hard Disk
• Keeps important things on the computer safe.
Did You Know?
We can do many things on a computer. We can listen to music, watch a video, and even get printouts.
Speakers use magnets to create sounds.
We can also store information in the computer, like our favourite songs, our school projects, films, and games. This is called data.
In the computer, data is stored in storage devices. Let us learn about them.
• Stores all that we have on the computer—including our favourite games, music, films, and projects.
CD/DVD
CDs and DVDs are both storage devices. They are used by putting them in the CD/DVD Drive.
Both the CD and the DVD are round in shape and look similar, but they are different in functioning. Let us see how!
CD
DVD
CD stands for Compact Disc. DVD stands for Digital Versatile Disc.
A CD holds less amount of data. A DVD holds a large amount of data.
Uses of CDs and DVDs
• These can be carried around easily.
• These help us in storing things like music, films, and homework.
Pen Drives
A pen drive is a small stick-like device in which you can store files. You can also transfer these files to another computer easily.
It is also called a flash drive. It is smaller than CDs and DVDs.
Uses of Pen Drives
• They can be used to easily transfer files from one computer to another.
• These are used to store a greater amount of data than CDs or DVDs.
• These, like CDs and DVDs, can be carried around easily.
Label the parts of the computer in the given image. 1
Computers work in a similar way. Let us see how.
Input: What we give to the computer.
Process: What the computer does with the input.
Output: What the computer gives us back.
Input, Process, and Output Cycle
Have you ever seen a plant grow? You give that plant water. The plant also breathes air. It also takes in sunlight. It takes in all these things and uses them to give us flowers and fruits!
This is called the Input, Process, and Output cycle or simply the IPO cycle. The IPO cycle tells us how a device works.
Let us see another example. This time, of a washing machine.
Input We put dirty clothes in the washing machine.
Process The washing machine washes the clothes.
Output We get clean clothes.

Computer Keyboard
We use a pencil to write on paper. But how do we write on a computer?
We use the keyboard.
The keyboard is an input device. It has lots of buttons, called keys, on it. It helps us type letters, numbers, and symbols on the computer. Let us learn about these keys.
Alphabet and Number Keys
Alphabet Keys
The alphabet keys are the keys with letters on them.
The computer keyboard is also called the QWERTY keyboard. It is based on the first six letters on the keyboard. Did You Know?
There are 26 alphabet keys, one for each letter in the English language. We use the alphabet keys to type words and sentences on a computer. The keys are arranged in such a way that they make typing letters easier.
Number Keys
The number keys are the keys with numbers on them. There are 10 number keys, from 0 to 9. These keys help us to type numbers on a computer. Some

Alphabet Key
Special Keys
There are many special keys on a keyboard. These keys are used to do particular tasks.
Let us learn about them.
Backspace Key
Sometimes, while typing, we make mistakes. We can correct them by erasing them.
The backspace key helps us remove the text or objects before the cursor (the blinking line).
Imagine we have typed ‘computerr’ by mistake instead of ‘computer’.
To fix this:
1. First, check if the cursor is at the right place. It should be after the letter to be erased, as shown.
2. Then, press the Backspace key.
Delete Key
Think and Tell
Which item in your pencil box works like the backspace key?
The Delete key also helps us remove text or objects but when they are after the cursor.
Imagine we have typed ‘machinee’. We can correct this mistake by clicking before the extra ‘e’ and pressing the Delete key.
To fix this:
1. Check if the cursor is before the extra ‘e’.
2. Press the Delete key.
computerr computer machine e machine
Punctuation Keys
Punctuation keys are used to add punctuation symbols. These symbols are the question mark (?), exclamation mark (!), full stop (.), comma (,), semi-colon (;), and colon (:).
Spacebar
The Spacebar is also called the Space key. The spacebar is the largest key on the keyboard. It adds a space between two words. Imagine we have typed ‘Ahorse’.
To fix this:
1. Check if the cursor is where we want to add space.
2. Press the Space key.
Caps Lock
Caps Lock key is used to type letters in capital.
If you press this key once, your letters will be in capital when you type. To write in small letter again, press the Caps Lock key again.
Think and Tell
Caps Lock: ON
Caps Lock: OFF I PLAY FOOTBALL i play football
Just like Caps Lock, is there a key on the keyboard that helps us to type capital letters?
Enter Key
The Enter key is used to move the cursor to a new line while typing. For example, imagine we have typed ‘I am a student. I study in grade 2’. To move the second sentence to the next line:
1. First, check if the cursor is before the sentence.
2. Then, press the Enter key.
Arrow Keys
I am a student. I study in grade 2. I am a student. I study in grade 2.
The arrow keys are four keys with arrows pointing in different directions.
They are used to move the cursor in the direction of the arrow.
Symbol Keys
The symbol keys have different symbols on them. For example, look at the number keys. They have symbols written above the numbers.
We can type these symbols using the Shift key.
Combination Keys
A combination is when two or more things are done together. So, a combination on a keyboard happens when we press two or more keys together. For example, Shift, Ctrl, and Alt.
Let us learn these keyboard combinations.
Shift Key
The Shift key is used to type symbols and punctuation marks present on the upper part of other keys. It is also used to type capital letters when the Caps Lock is turned off.
For example, we want to type ‘Hello!’. Let us first type the word ‘Hello’.
Then, to add the exclamation mark (!), we will press and 1 together.
Control (Ctrl) Key
The Ctrl key is used with other keys to create shortcuts. For example, copying (Ctrl + C) or pasting (Ctrl + V).
Alternate (Alt) Key
The Alt key is used with other keys to do special tasks. For example, switching between windows (Alt + Tab).
Did You Know?
The combination Ctrl + Alt + Del is used to open the task manager, restart, log out, and change the password of a computer.

Understanding the Mouse
We learnt that we could do so many things on a computer like listen to music, play games, and even study.
Look at the part of the computer that is labelled here.
1. Do you know what it is called? It is called the mouse!
2. When you move the mouse, an arrow also moves on the computer screen. This arrow is called the pointer.
Think and Tell Mouse
Is mouse an input device?
A mouse has three parts—a left button, a right button, and a scroll wheel.
The mouse was invented by Douglas Engelbart in the 1960s. Did You Know? Left Button Right Button Scroll Wheel
But how do these parts help us?
• Left Button: helps you click on things you want to open or use on the computer.
• Right Button: opens up additional options.
• Scroll Wheel: helps you move a page that is open on the computer screen up and down.
Holding a Mouse
Now, let us learn how to hold the mouse properly. To hold a mouse properly, put your hand on top of it in such a way that:
1. Your index finger should be on the left button.
2. Your middle finger should be on the right button.
3. Your thumb and the other two fingers should be on the sides of the mouse.
Left Button Right Button Index Finger
Middle Finger
Thumb
Other Two Fingers
Discuss! Does the mouse work when it is in the air? Why or why not?
Now, move the mouse on the table. See how the pointer on the monitor also moves.
Colour the parts of the mouse with these colours: left mouse button in orange, right mouse button in blue, the scroll wheel in red and the body of the mouse in green.
Mouse
Pointers
The mouse pointer is the little arrow on the monitor that moves when we move the mouse. It helps you to point at, select, and click on many things that you see on the monitor.
At first, the mouse pointer is simply a white arrow with a black border.
What if we don’t like this arrow? Can we change it? Yes, we can!
There are many other types of mouse pointers. Let us look at some of them.
Explore More!
Find out how your mouse pointer can be changed.
Using the Mouse
We have learnt what a mouse is and how to hold it. Now, let us learn how to use it.
Clicking
Pressing a mouse button is called clicking. We hear a soft clicking sound when we press the mouse buttons.
Clicking with the left button is called a left-click. With one left-click, we can select an item.
Clicking the left button two times, very quickly, is called a double-click. When we double-click the left mouse button, it will open the selected item.
Scrolling
Clicking with the right mouse button is called a right-click. When we right-click, we get a list of choices that we can select.
Rolling the scroll wheel up and down using your index finger is called scrolling. Scrolling moves the page that is opened on the monitor up and down.
Drag and Drop
1. Select a file by left-clicking on it.
2. Then hold the left mouse button and move the mouse without leaving it. Moving the mouse without leaving the left mouse button is called dragging.
3. When you release the left button, you will see the file is placed where the pointer is.
4. This way of moving the file is called drag and drop.

c The default mouse pointer is a white arrow with a black border.
to Remember
The mouse is an input device that helps control the pointer on the monitor.
The mouse consists of three main parts: left button, right button, and a scroll wheel. Mouse pointers look like arrows on the monitor. They move in the same direction a mouse is moved.
To hold a mouse correctly, position your index finger on the left button, middle finger on the right button, and thumb and other fingers on the sides.
The left mouse button is used to click on, select, and open items on the monitor. The right mouse button provides additional options for the selected item. The scroll wheel helps in scrolling up and down on the monitor.
Left-clicking on an item selects it, while double-clicking opens the selected item.
Right-clicking on an item brings up a menu with a list of options for a selected item.

Introduction to Robots
All of us love going to toy stores. Playing with toys is so much fun. We see many toys around us, like teddy bears, rabbits, and dolls.
But what is this toy that looks like a person? It can also walk on its own! This is a robot. But, what are robots?
A robot is a machine that can do things on its own.
Some robots can move around and some can even pick things up. We even have robots that look like humans and can talk as well!
How Do Robots Work?
We know that robots can do things on their own. But how do they do that?
Discuss! Is a torch a robot?
They can do all these smart things using AI, which stands for Artificial Intelligence. With AI, machines are made to act like they understand and think. AI also helps machines to learn things.
So, when you talk to your ‘smart’ robot, the AI helps the robot to understand you. It also helps the robot to reply.
High-tech Robots in Our World
There are many robots in the world that scientists have invented.
Sparko
Sparko, the first robotic dog, was developed in the USA in the 1940s.
It can:
• walk and run.
